To (LZZ whowt it T11/my 0071/067017,.-

Be it known that l, HERBERT MoConNAoK, a citizen of the United States,residing at Westchester, county of Chester, State of Pennsylvania, haveinvented certain new and useful Improvements in Centrifugal Separatore,of which the following is a specification,

My vinvention relates more particularly to that class of centrifugalseparators in which a bowl or vessel of elongated or tubular form isemployed in connection with a casing for said vessel and asuitably-suspended shaft, to the lower end of which the vessel isremovably coupled.

My main object is to provide a simple form of frame comprising an uppershaft-support ing portion and a lower fixed casing for the vessel soarranged as to permit the convenient insertion and removal of theuncoupled vessel, as fully described in connection with the accompanyingdrawing, and particularly pointed out in the subjoined claim.

The drawing shows a sectional elevation of a centrifugal machineembodying my invention.

The shaft mechanism shown in the drawing is particularly described andclaimed in my pending application, Serial No. 185,007, filed December14, 1903, and the general arrangement is similar to that shown in PatentNo, 7 06,088, issued to me August 5, 1902.

The centrifugal vessel 1, of tubular form, is separably coupled to ahanging shaft 2, which is carried upon a top bearing 3 provided in theframe of the machine, and the hollow lower end 4L of said pendent vesselis provided with a steadying bearingI mounted in the lower portion ofthe casing 5,"which incloses the vessel. The rapid rotation of thehanging vessel 1, by means of the shaft 2 and the driving mechanismtl1erefor,While feeding a compound liquid, such as milk, to said vesselthrough the bottom inlet 6 edects the separation of the liquid into itsconstituent parts, which are separately discharged through outlets 7 and8, respectively, into separate milk and cream pans 9 and 10, supportedupon the casing 5.

The shaft 2, as shown, is mounted in a shaft-casing 13, forming with thedriving-gear casing 14 a portion of the frame of the machine. Its upperend is carried upon the suspension-bearing 3, while its lower dependingportion passes loosely through the bearingsleeve 16 and is provided atits projecting end with a suitable coupling' 18, by means of which thecentrifugal vessel 1 is connected. or disconnected. It is very desirablethat this suspended shaft shall not be disturbed in position,notwithstanding the necessity of frequently uncoupling the vessel andlifting it out of the casing 5 for cleaning or other purposes. Toprovide for conveniently accomplishing this while making the casing 5 arigid portion of the frame of the machine, I so form the said fixedcasino as to adapt it to serve the purposes of incloslng the full lengthof the tubular vessel and supporting the lower end thereof, While at thesame time permitting the disconnected vessel to be tilted out ofalinement with the shaft above sufficiently to enable it to pass clearof the shaft-inclosing portion of the frame above the coupling 18 whilethe vessel is being lowered into or raised out of the casing. (Seedotted lines.) The `lower end ofthe vessel is normally maintained,approximately, in axial alinement with the shaft by means ofa suitablebearing in the casing and is supported by the casing when uncoupled.from the shaft, while the wall of the casing is spread to permit the lateral tilting of the vessel, as indicated, when the milk and cream pans 9and 10 are removed, thus enabling it to be readily passed clear of theshaft-inclosing portion of the frame above the casing either ininserting or removing the vessel from the latter.V

1t will be seen that by means of my inven tion I am able to employ asimple and rigid frame construction while providing for read ilyremoving the vessel without interfering with the mountingof the shaft.
